Working principle:

when the belt 12 is not used for transporting mineral aggregate, the top ends of the supporting rollers 41 are not pressurized, so that the springs 55 normally push the corresponding shaft rods 56, the second meshing toothed plate 5 and the tensioning rollers 51, and the tensioning rollers 51 are contacted with the lower wall of the inner ring of the belt 12 and are extruded, so that the belt 12 is automatically kept in a tensioning state;

when the belt 12 transports mineral aggregate, the material falls on the surface of the belt 12, the top ends of the supporting rollers 41 are pressed, the supporting rollers 41 move downwards together with the first meshing toothed plates 4, at this time, the first sliding strips 42 on two sides of the first meshing toothed plates 4 slide in the corresponding sliding grooves in an auxiliary manner, due to the downward movement of the first meshing toothed plates 4, the gear roller 6 is driven to rotate, and finally the second meshing toothed plates 5 are driven to move upwards (because the two meshing toothed plates are symmetrical with respect to the gear roller 6), at this time, the tensioning roller 51 is not in contact with the lower wall of the inner ring of the belt 12 (the belt 12 is prevented from being stretched due to excessive tensioning force), the upward movement of the second meshing toothed plates 5 pushes the plurality of shafts 56, and then pushes and compresses the plurality of springs 55, so that the springs 55 obtain an elastic restoring force, and when the weight of mineral aggregate on the surface of the belt 12 is reduced, the springs 55 push the corresponding shafts 56, and continue to enable the tensioning roller 51 to descend into the tensioning operation of the belt 12.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
